'I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part ot' this specication, in which- Figure l is an end view of my invention; Fig. 2, a side view ofthe same; Fig. 3, a side view ofthe block or water-way, partly in section; Fig. 4, a detached section ot' one of the Wheels, taken in the line x w, Fig. 5; Fig. 5, a detached inner side view of Fig. 4; Fig. 6, a section of a portion of Fig. 3, taken in the line Similar letteisr .of reference indicate like parts.

This invention relates to anew and improved water-wheel, which is also applicable forA use with steam as a motor.

The invention consists in the employment or use of two Wheels placed on one and the same shaft, with a block between them, having water y ways or passages made in it, and all arranged to operate as herein set forth.

A represents a block, through which a shaft, B, passes loosely and is allowed to rotate freely, said shaft having two wheels, C C, keyed or otherwise secured upon it, oneat each side of the block A. (See Fig. 1.) rlhe wheels U U run in close contact with the sides ofthe block A, and they may be described as circular disks notched or scooped out at their inner sides to form buckets a, the shape or form of which will be fully understood by referring to Fig. 4.

The block A has an opening or passage, b,

grooves d in the sides of the block A.

made in it, which is divaricated at its inner end to form two outlets, c c, which communicate with the lower ends ot' spiral grooves or passages d, made one in each side ot' the block A, said grooves or passages being in the form of a semicircle equal in width to the buckets and extending around one-halt the wheel, the grooves being deepest, or extending into the block A to the greatest depth, at the lower ends and gradually decreasing in depth to their upper ends, where they are Hush with the exterior of A.

In the block A, adjoining the upper ends of the grooves or passages d d, there is an openy. i ing, c, which serves as an escape. y

The operation will be readily understood. The water is admitted into the opening or pas` sage b, and is conducted by the passagescclto the buckets a of the two wheels C C, against l which it acts, the water escaping from the buck-z` ets as the latter pass the upper ends of`lthe When the device is used as a water-wheel, i` one-quarter of the block A may be removehas indicated by the dotted red lines in Figip. i I For steam l design to have the exhaust at l I claim as new and desire to secure by Let-jm? ters Patentp The two wheels O G, provided with buckets a, as shown, and keyed on one and the same shaft, B, in combination with the block A, provided with the water-passages b c c, grooves d d, and escape-passages e, all arranged to operate substantially as and for the purpose set forth. y
